Question

How to calculate quickly in chemistry physics?

Answer 1

To calculate quickly in chemistry and physics use approximation method,for eg
$= \frac{56789}{1523489} \\ = \frac{56789}{1.523489 \: \times {10}^{ 6} } \\ = \frac{56789 \times {10}^{ - 6} }{1.5} \\ = 3785.93 \times {10}^{ - 5} \\ = 0.03785$
by this way just minimize the denominator term
